GASOLENE-BURNER.

Specification of Letters Patent. Patented Juil@ 20, 1911.

vApplication filed June 27, 1910. Serial No. 569,114.

To all whom 'it may concern.:

lie it known that l, ALBERT S. FREEMAN. a citizen of the United States,residing at Alexandria, in the county otl Madison and State oflndiana,have invented a new and useful (iaSolene-Burner, of which the followingis a specitication.

The object of my invention is to produce an apparatus, more especiallydesigned for ready attachment to existing hot water ree.-

ervoirs, by meansl of which water may be heated by gas producedby theapparatus from a supply of gasolenetor other ein'iilar volatile fuel.

The accompanying drawings illustrate my invention.

Figure l is an elevation in partial vertical section of my improvedgeneratorI and heater; Fig. 2 an elevation at right angles to Z0 that,shown in Fig. l and with the inclosing casing omitted, and Fig. 3 anelevation ot' the complete apparatus associated with the waterreservoir. y

In the drawings, l() indicates a flat thin hollow body or heatingchamber within which may be maintained a comparatively thin body ot'water. Leading into the bottom of the heating chamber l() is an inletpipe, ll and leading from` theI top of said chamber a discharge pipe l2.rl`he pipe ll'is adapted for connection with the lower region otf thewater rcservoir lZ-i and the pipe l2 is adapted for connection with theupper regions oi' .said reservoir. 'l`be upper end of the body l() isprovided with a linger or bracket l-l to which l .secure a hollowcrosshead l5 provided with oppositcly extending down-turned branches lo,lt, and a ccntral upward receiving branch IT into which i.s

40 secured the lower end otl a mixture pipe t8. Secured to Ieach branchlo and depending therefrom alongside ot a tlat face ot the main body l()is a gas pipe 1S) provided with a plurality of laterale 2t which extendtoward the adjacent tlat face of body 1t).

` Secured to the, outer end of each olf the laterale 2l is a suitable,burner nipple or nozzle 22, so arranged as to direct the burning uponthe adjacent flat tace ot body 1.0.

Secured to the upper end ot' pipe i8 is a tubular cap23 provided with acentral mix ing tube 2li into the open upper end of which is directed anozzle 25 in which is mounted an ordinary controlling needle l turn.

valve ope ated by a head 26 Secured thereto. .l-lead 2o provided with adepending` linger I' adapted to engage a lateral 25', forming part ofthe nozzle 25, so as to limit the movef ment of the head 2G to about onecomplete 60 Nozzle 25 is integral with superheater tube 2S) which isSupported in an ex tension 23 of the cap 23. The Superheater tube 2t)extends alongside of the mixture tube 1S and at ita lower end it isconnected 65 by a suitable coupling il with Aa generator or vaporizingpipe 32. The pipe 232 extends for a short distance do\\' 1nvardly fromthe lower end of the supcrheater tube il along' side one llat face ol'body l() and passes 70 from thence upwardlyvto a couplingl 33 by meansof which it mayl attaehed to a valve body Bl in which is mounted `a.suitable con.- trolling valve il?) by mean-L of which the tlow ofgasoleue lo pipe 32 may be controlled. 75 Leading into the valve bodylisa suitable supply pipe :it which may be connected to any suitablesource ot' fuel Supply, as for instance the ordinary pressure tank 37.

rl`he entire generator and heater structure may bereadily incased by atubular casing 1li) sleeved down over the ystructure and supportcd uponcap 'li as cl url v shown in l*`ig. l uml as indicated b v dotted linesin Fig. Il.

Leading upward trom the hollow head l5 85 is asmall pipe 4l to thc upperend ot' which is attached a suitable burner t2 which is directed towardthe .supcrluatcr tubo lil and the mixture tube i8.

rl`he operation is as lfollows: To start the e apparatus, nozzle 25 islirst heated by any suitable means7 such lor instance as an ordi* nan'gasolene torch. When the nozzle 25 has been properly heated valve 35 andthe valve controlled by head Qt are opened aud lgasolcne (lows from headS4 down through pipe 32, thence upwardly through the superheater pipe2t) and nozzle Q5 where it is vaporized and passes Jfrom thence throughmixture. tube v1% and from thence, through theI branches lt' to pipo lt)and emerges through the burners Q2 against. the flat faces of the heaterbody lt). Atthe same time a portion of this gas rises from the head 'l5through tube 4t to the burner 42 and is lighted7 whereupon the flame'from this burner 42 envclops the Supcrhtulter tube. 2t) and themixture. tube t8.

l have found from practice that it is desi 'able to heat 'the gasolenefeed tube at a charge therefrom to the mixer because otherwise thevolatilized fuel is not suliicicntly het to properly mix with the air. Ialso iind that it is desirable that the mixture of gas' and air be alsothoroughly heated before it'- reaches the burners, as by that means I amable to secure a proper noirexplosive mixture of gasolene vapor and airwhich, because of its high heat, will burn with prac-` tically acolorless llame against the water cooled walls et' the heater body 10.

"1y the arrangement shown I am enabled to practically entirely envelopthe water heater body l0 and, because ot' the thinness ot the column otwater in the body, to heat the said column almost instantaneously. Byturning head 2G in closing direction until linger 2T engages lateral 25,the nozzle valve is brought to a point where just a sutlicient amountot' gas will emerge to maintain the burner l2 in generating condition,while by turning the head 2G in the opposite direction to its l'ullamount the maximum supply o' gas is obtained.

It will be readily understood that the geir erato`r described herein maybe used in connection with other forms ot' heaters.

'lhc particailar -l'orm of heater shown is readily attachable toexisting watertjanks which are now commonly found either in connectionwith water backs of coal burning ranges or provided with heaters ofvarious kinds capable of burning illuminating lt will be noticed that,in the arrangement I have shown, the gasolene is vaporized in the tube32 because that tube passes down alongside the heater body l() and comeswithin the influence of the flames ironi the' adjacent burners Thegasolene vapor thus'produced in the tube 32 expands into the largersuperheat'er tube 2t) where it is Supcrheated by the burner d2. It isalso to be noticed that, by reason of this heating ot gasolene vapor, Iam able todischarge the vapor through a downwardly, presented nozzlethus making it possible to bring the nozzle valve and the gasoleneIvalve 35 to the upper part of the structure where they can be readilymanipulated. Thetstructure however is of such character that it willwork satisfactorily in any position of direction of the nozzle 2 Iclaim. as my invention' i l. The combination of a mixture tube, twoburner nozzles leading from the mixture tube, a vaporizing tube carriedthrough the heat-ing zone of one ,of said burner nozzles, a superheatingtube receiving the discharge from the vaporizing tube and carriedthrough the heating zone of the other of said burner nozzles, andanozzle receiving the discharge from said superheating tube and discharging into the mixture tube, the initial portion of the mixturetube alsolying in the heating zone of one of said burner nozzles.

2. A vapor burner comprising a mixture tube, a. super-heater arrangedalongside the mixture tube, a nozzle leading from the super-heater tubeand directed in to the mixture tube a. valve for controlling the outflowfrom said nozzle, a vaporizing tube leading to the super-heater tube, aburner nozzle leading from the mixture tubd and having a heating zonethrough which the vaporizing tube passes, and a second burner' nozzleleading from the mixture tube andidirected toward the super-heatertube-and initial end of the mixture tube whereby said super`` heatertube and initial end of the mixture tube will lie in the heating zone ofsaid second burner. Y

In witness whereof, I have hereunto set my hand and seal atIndianapolis, Indiana.
